MIMO Channel Capacity Simulation

This article provides a concise introduction to MIMO channel capacity simulation, aiming to investigate the variation patterns of channel capacity through calculation and visualization methods, thereby enhancing understanding of MIMO systems. Channel capacity refers to the maximum data transmission rate achievable under specific signal-to-noise ratio (SNR) conditions. Through MIMO channel capacity simulation, we can better comprehend the advantages and limitations of MIMO systems, offering valuable insights for system design and optimization. The implementation typically involves calculating the capacity formula C = log₂ det(I + SNR/N_t * H*H') for each SNR point, where H represents the channel matrix and N_t denotes the number of transmit antennas. Visualization scripts then plot capacity versus SNR curves using MATLAB's plot function with proper axis labeling. Although this article presents preliminary simulation results, further research and exploration can deepen our understanding of MIMO system performance and its application prospects in future communication systems.
